Here are two examples of ESCape code sequences:

LPRINT CHR$(27)CHR$(71)

LPRINT CHR$(27)CHR$(38)CHR$(@)CHR$(l)CHR$(3)

To see how such sequences work, start a new program now by

entering:

10 LPRINT CHR$(27)CHR$(52)

20 LPRINT "ITALIC CHARACTER SET"

and RUNning it. When you can RUN a program, we show you the

results that you should expect:

ITALIC CHARACTER SET

Note: If you haven’t yet read the Preface, which includes “Conven-

tions Used in This Manual,” this is the time to do it. Especially

important now are the passages on semicolons and on saving

programs.

The FX interprets the

CHR$(27)CHR$(52)

sequence in line

above as

a command to switch from Roman to Italic characters. The LPRINT

in line

sends a string of characters to the printer to verify that the

printer is in Italic Mode.

Now type:

LLIST

(or your system’s version of the print LIST

command)

to check the printer’s status as in Figure 2-1:

Figure 2-1. Italic listing

Since all the text is still printed in Italic characters, you can see that this

mode stays on until it is turned off. This is typical of the modes on FX

printers: nearly all modes stay on until turned off. We will alert you to

the few exceptions.

If your printer is printing one line on top of another or if it is double

spacing, you need to change the setting of the FX’s DIP switch

2-4.
